Definitions
- the general field of the invention relates generally to power electronics and more particularly to improving reliability and maintainability of DC-AC inverters, and even more particularly to increasing reliability and maintainability in the inverters used in solar array applications.
- Distributed power harvesting systems include series connections of many DC power sources or parallel connections of many AC power sources or modules to accumulate the power from each source. Batteries with numerous cells or hybrid vehicles with multiple fuel cells are examples of DC power sources whose power is accumulated through a series connection. Maintaining reliability in such connections is important because malfunction of one component in a series connection may disturb the operation of the entire installation. Solar energy is an example of a technology that is based on distributed power harvesting from DC power sources.
- PV cells forming solar arrays provide a clean alternative source of energy.
- Solar installations include PV panels that convert the light energy to electric power and electronic power harvesting systems that harvest the electric power from the panels and convert it for domestic use. In a typical domestic installation, the power will ultimately be inverted to AC so it could be used by electrical devices or fed into the grid.
- FIG. 1 A conventional centralized system for distributed power harvesting, is shown in Figure 1 .
- DC power sources such as PV panels 101
- PV panels 101 are connected in series to form a string of panels 103.
- strings 103 may be connected in parallel.
- the PV panels are mounted out-doors, and their leads are connected to a maximum power point tracking (MPPT) circuit 107 and then to an inverter circuit 104.
- MPPT 107 and inverter 104 circuits may be elements of a single product and housed in the same inverter box.
- the MPPT circuit 107 tracks the maximum power point where the current extracted from the PV panels provides the maximum average power such that if more current is extracted, the average voltage from the panels starts to drop, thus lowering the harvested power.
- the MPPT circuit 107 maintains a current that yields the maximum average power from the series connected panels 101 or the parallel connection of the strings 103.
- the harvested power is then delivered to the inverter 104, which converts the fluctuating direct-current (DC) into alternating-current (AC) having a desired voltage and frequency which is usually 110V@60Hz or 220V@50Hz.
- the AC current from the inverter 104 may then be used for operating electric appliances or fed back to the power grid.
- the power extracted from the inverter may be directed to a conversion and charge/discharge circuit which charges batteries. The batteries could store any excess power created until it is needed.
- the centralized system shown in Figure 1 has a number of limitations and drawbacks, which adversely affect its ability to harvest all of the potential power, and may limit the functional lifetime of the installation.
- the limitations of the centralized system include low tolerance to panel aging and panel malfunction. Further, large variations in the voltage entering the inverter causes components in the inverter to be more susceptible to degradation, thus lowering their useful lifetime. It is interesting to note that although PV panels may have warranties in excess of 20 years, warranties on inverters are usually only 5 years.
- the inverters include capacitors that over time either malfunction or their functional parameters change over time due to stress or aging.
- the inverter often malfunctions because of problems in the on-board capacitors.
- a technician must be sent to the premises to replace the inverter, even if there is a single capacitor at fault.
- One reason is that the replacement of capacitors requires disassembly of the inverter and either soldering out the faulty component or replacing the entire circuit.
- inverters In practice inverters generally fail and need to be replaced several times over the life of a solar system. These failures require dispatching of a professional technician to diagnose the problem and replace the inverter when needed. Often the failure is traced to the capacitors, which fail due to prolonged service under stress. These capacitors are rated for high capacitance on the order of, for example, 100 ⁇ F - 20mF for the inverter input capacitor and several ⁇ F for the output capacitor (e.g., 1-10 ⁇ F). At times, failure of the capacitor may cause a short circuit, which may cause further irreparable damage to the inverter, or possibly other elements of the system. Therefore, any improvement in the reliability and/or ease of service of the inverter would greatly benefit the overall service of the solar system. Also, any improvement enabling preventive maintenance would be of great benefit for solar systems and, in fact, for other electrical systems utilizing inverters.
- a novel approach is proposed that drastically simplifies diagnosis and repair of DC-AC inverters, even by casual users. Moreover, the novel approach introduces means for preventive maintenance that cannot be performed in conventional inverters. Consequently, the service of the overall system is enhanced.
- a power harvesting system comprising: a power source providing DC power; and an inverter coupled to the power source and receiving and inverting the DC power into AC current, the inverter comprising: a housing; an electrical circuit situated within the housing; and at least one removable cartridge electrically contacting the electrical circuit and housing at least one electrical component therein.

- the power source may comprise a DC-DC converter, the converter comprising a replaceable component cartridge.
- the replaceable component cartridge may house at least one capacitor.
- the capacitor may be rated at 1 ⁇ F - 20mF.
- the inverter may further comprise a controller providing an indication when the removable cartridge should be replaced.
- the controller may determine to provide the indication by testing the parameters of the electrical component within the cartridge or by timing service life of the electrical component within the cartridge.
- the inverter may further comprise a reset button providing an indication to the controller when a cartridge has been replaced.
- a solar power system comprising: a plurality of solar panels; a DC-AC inverter coupled to the solar panels and receiving direct current generated by the solar panels, the inverter inverting the direct current into alternating current; wherein the DC-AC inverter comprises a circuit board having an integrated circuit disposed thereupon, and a removable cartridge attached to the board, the removable cartridge housing electrical components coupled to the integrated circuit via the board.

- the capacitor may be rated at 1 ⁇ F - 20mF.
- the removable cartridge may comprise mechanical clamp affixing the removable cartridge to the board.
- the solar power system may further comprise a plurality of DC-DC converters, each converter being coupled to one of the solar panels.
- the solar power system may further comprise an indicator providing an indication when the cartridge should be replaced.
- the indicator may comprise a timer.
- the solar power system may further comprise means to reset the timer.
- a removable cartridge for use in electrical circuits comprising: a housing; electrical connectors affixed to the exterior of the housing; and at least one capacitor or active element housed within the housing and electrically connected to the electrical connectors.
- the cartridge may further comprise mechanical clamp provided on the exterior of the housing.
- an inverter comprising: a housing; electrical circuitry provided within the housing; and a removable cartridge housing electrical component, the removable cartridge having contacts connected to the electrical circuitry and to the electrical component.
- the inverter may further comprise a plurality of switching transistors and a controller activating the transistors.
- the inverter may further comprise means for indicating when the cartridge should be replaced.
- the means may comprise a timer.
- the means may comprise a testing means within the controller.
- the inverter may further comprise a reset means for resetting the timer.
- the means may comprise a test of capacitance or leakage current of capacitor within the removable cartridge.
- the reliability cartridge isolates any components prone to malfunction on a user removable part. Because the faults usually occur in the capacitors, the capacitor components would be prime candidates for the replaceable reliability cartridge.
- the reliability cartridge may include other components as well, such as active elements, e.g., FET (field effect transistor) and/or IGBT (isolated gate bipolar transistor).
- Distributed power harvesting systems provide a system for combining power from multiple direct-current electrical power sources.
- the power sources are each connected as inputs to an associated electrical power converter.
- Each electrical power converter converts input power to output power by monitoring and controlling the input power at a maximum power level.
- Outputs of the electrical power converters are connected into a series-connected direct-current output.
- An inverter may be used to invert the series-connected direct-current output into an alternating-current output. The inverter controls voltage of the series-connected direct-current output at a previously-determined voltage by varying the amount of current drawn from the series-connected direct-current output.
- each converter may be coupled to an associated inverter to form an AC module.
- the AC modules may be parallel connected to accumulate power.
- each electrical power converter substantially all the input power is converted to the output power, and the controlling is performed by fixing the input current or voltage to the maximum power point and allowing output voltage to vary.
- a controller may perform the controlling by adjusting duty cycle using pulse width modulation (or any of numerous other methods such as PFM [pulse frequency modulation]) transferring power from the input to the output.
- the direct-current electrical power sources may be solar cells, solar panels, electrical fuel cells, electrical batteries, and the like.
- one or more sensors perform the monitoring of the input power level.
- FIG. 2 illustrates a distributed power harvesting and conversion configuration 40, according to an embodiment of the present invention.
- Configuration 40 enables connection of multiple power sources, for example solar panels 401 to a single power supply.
- the series connection of all of the solar panels is connected to an inverter 404.
- each solar panel 401 is connected to a separate power converter circuit 405.
- Power converter circuit 405 adapts optimally to the power characteristics of the connected solar panel 401 and transfers the power efficiently from input to output.
- Power converters 405 can be buck converters, boost converters, buck/boost converters, flyback or forward converters.
- the converters 405 may also contain a number of component converters, for example a cascade of buck and boost converters.
- Each converter 405 includes a control loop that receives a feedback signal, not from the output current or voltage, but rather from the input coming from the solar panel 401.
- An example of such a control loop is a maximum power point tracking (MPPT) loop in solar array applications.
- MPPT maximum power point tracking
- the MPPT loop in the converter locks the input voltage and current from each solar panel 401 to its optima! power point.
- the MPPT loop of the converter 405 operates to perform maximum power point tracking and transfers the input power to its output without imposing a controlled output voltage or output current.
- Converters 405 can be connected in series or in parallel to form strings and arrays.
- Conventional DC-to-DC converters have a wide input voltage range at the solar panel side and an output voltage predetermined and fixed on installation.
- the controller monitors the current or voltage at the input, and the voltage at the output.
- the controller determines the appropriate pulse width modulation (PWM) duty cycle to fix the output voltage to the predetermined value increasing the duty cycle if the output voltage drops while varying the current extracted from the input.
- PWM pulse width modulation
- the controller monitors the voltage and current at its input and determines the PWM in such a way that maximum power is extracted, dynamically tracking the maximum power point.
- the feedback loop is closed on the input power in order to track maximum power rather than closing the feedback loop on the output voltage as performed by conventional DC-to-DC voltage converters.
- the outputs of converters 405 are series connected into a single DC output into the inverter 404 which converts the series connected DC output to an alternating current power supply.
- the circuit of Figure 2 provides maximum power available during continuous operation from each solar panel 401 by continuously performing MPPT on the output of each solar panel to react to variations in temperature, solar radiance, shading or other performance deterioration factors of each individual solar panel 401.
- conventional prior art solutions for combining power perform MPPT on strings 103 or arrays of solar panels 101.
- each string 403 in the embodiment shown in Figure 2 may have a different number of panels 401 connected in series.
- panels 401 can be installed in different directions, as solar panels 401 do not have to be matched and partial shading degrades the performance of only the shaded panel.
- the MPPT circuit within the converter 405 harvests the maximum possible power from panel 401 and transfers this power as output regardless of the parameters of other solar panels 401.
- FIG 3 is a simplified schematic drawing of an inverter.
- An inverter converts the DC electricity from sources such as batteries, solar panels, or fuel cells to AC electricity.
- the inverter shown in Figure 3 includes capacitors 300, 310, switches 320, 330, 340, and 350, and a transformer 360.

- the switches 330 and 340 are on, a negative current is provided from the capacitor 300 to the capacitor 310.
- an alternating current reaches the transformer 360.
- Antiparallel diodes may be connected across each semiconductor switch 320, 330, 340, 350 to provide a path for the peak inductive load current when the semiconductor is turned off.
- the capacitor 300 is an input capacitor and is used on a DC side of the inverter for storing and filtering the incoming energy. Capacitor 300 is generally rated at 100 ⁇ F - 20mF. The capacitor 310 is used on the AC side of the inverter for storing energy that is passed onto the AC side through the transformer 360. Capacitor 310 is generally rated at several uF, e.g., 1-10 ⁇ F.
- each of the capacitors 300, 310 may include several capacitors connected together in parallel to obtain a larger capacitance value.
- the switches may be FET or insulated-gate bipolar transistors (IGBTs).

- the reliability cartridge 300 is removable and may be replaced with another cartridge containing an equivalent element. Replacement may be performed as routine maintenance or upon failure of the element contained in the reliability cartridge.
- the controller is programmed to perform performance check of certain components, such has the capacitors, and provide reports or alarms when it is determined that a component functions below its required performance characteristics.
- the controller may also be programmed to include a counter that provides an indication of expiry of service life of components. The counter may be reset each time a component is replaced.
- the reliability cartridge 300, or any other reliability cartridge is used to isolate any elements prone to malfunction on a removable part. As a result, only faulty components are replaced upon failure. Further, replacement of the reliability cartridge is simple and could be performed by an unskilled user. Preventative maintenance is made possible because the owner could be sent a replacement cartridge before failure or replace the component when the controller provides indication that the component performs below requirement or that a service life has expired.
- the reliability cartridge 400 is shown as including a capacitor.

- the replaceable component cartridges 710 730 are connected to the exterior of the box, so that the user may replace the cartridges without having to open the box 700.
- the cartridges may be removed by simply pulling on the cartridge to separate the cartridge from the electrical sockets (not shown) it is connected to.
- mechanical clamping may be provided to physically secure the cartridge to the inverter housing 700.
- the arrangement illustrated in Figure 7 provide a safety measure to enable easy replacement of components by non-trained persons without the risk of electrocution. It also ensures that non-trained persons do not have access to the other circuitry of the inverter so as not to damage the inverter. Another benefit is that the supplier of the inverter can monitor tempering with the inverter for warranty and other purposes.
- each cartridge 710, 730 is shown, each having an indicator light 705, 725, that provides an indication of whether the cartridge should be replaced.
- the controller may perform performance check on the component (e.g. capacitance or leakage current of capacitors) or may include a timer that measures the life of the component.
- optional reset buttons 715, 735 are provided. Whenever a cartridge is replaced, the respective reset button may be depressed, to thereby indicate to the controller that the cartridge has been replaced. For example, when a timer is used to measure the components service life, the reset button may restart the counter upon replacement of a cartridge.
- each cartridge may have a unique ID or other means of identification so that when it is replaced, the inverter control circuit can be automatically aware of the replacement and function accordingly.
- Figure 8 illustrates another inverter according to an embodiment of the invention.
- the embodiment of Figure 8 is similar to that of Figure 7 , except that in Figure 8 a cover 740 is provided so that the housing 800 encloses the entire inverter, including the removable cartridges.
- Box 820 may be opened by, for example, removing simple or temper proof bolts 845, or other such means.
- the cartridges may be replaced by a user without the need for any tools or soldering.
- the reliability cartridge may be used to contain different components and may be used with different parts of the power harvesting circuit
- using this cartridge in the inverter circuit provides ease of operation. Because, in a PV power harvesting system, each panel has a power-converting circuit, the voltage entering the inverter is substantially constant and does not fluctuate as function of the luminance and aging of the panel. Therefore, a more robust inversion circuit may be designed, which allows for a large gamut of component values to be used.
- the inverter is substantially insensitive to the exact values of the components used and is much more tolerant to drift in the values, which is common as components age. This robustness directly leads to tolerance to problems that may emerge and longer average lifetime of the system.
- the use of electrolytic capacitors in the panel modules may be eliminated, thus greatly extending the life of the modules.
- ASICs Application specific integrated circuits
- ASICs Application specific integrated circuits
- the probability of manufacture related failures is proportional to the number of components used, the integration of the complex functions of several components into one ASIC component reduces the chance of failure.
- several components of the inverter circuit or other circuits used in the system of Figure 2 may be implemented using ASICs. In that case, reliability cartridges including each ASIC may be used that are easily replaceable.
